COTTON-CHOPPING- MAUHINE.

Specification of Letters Patent.

Patented May 31, 1910.

Application filed October 19, 1908. Serial No. 458,486.

To all whom it may concern:

Be it known that I, JOHN M. MARTIN, citizen of the United States,residing at Frisco, in the county of Collin and State of Texas, haveinvented certain new and useful Improvements in Cotton-ChoppingMachines, of which the following is a specification.

My invention relates to new and useful improvements in cotton choppingmachines.

The object of my invention is to provide a cotton chopping machine whichwill carry a mechanically driven hoe which will properly space and chopcotton stalks.

Another object of my invention is to provide in a cotton choppingdevice, a machine which will be attached to the frame of a standardcultivator and thin the cotton as the ground is being cultivated.

Still another object of my invention is to provide a cotton choppingmachine which will automatically adjust the chopping means for high andlow ground while the machine is in motion.

A final object of my invention is to provide a cotton chopping devicewhich will be strong, durable, efficient and comparatively inexpensiveto construct, and also one in which the several working parts will notbe liable to get out of working order.

With these and other objects in view, my invention has particularrelation to certain novel features of construction and operation, anexample of which is described in the following specification andillustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation of my machine, Fig. 2 is a rear elevationof the same, and Fig. 3 is a plan view with a portion of the arch brokenaway.

In the drawings, the numeral 1 designates an arched axle mounted onground wheels 2 and having connection with a tongue 3 through connectingrods 41. A sprocket wheel 5 on the axle carries a clutch member 6adapted to engage with a clutch member 7 carried on the ground wheels 2.A lever 8 fixed to operate this clutch is also mounted on the axle 1.

An arch 9 supported from the connecting rods 1 has outwardly extendingarms 10 arranged to form a support for any suitable cultivator gang organgs. A frame 11 mounted on ground wheels 12 carries rollers 13arranged to engage with the downwardly extending portions of the arch 9in such a way as to allow the frame to be raised or lowered by theground wheels 12 and still maintain its horizontal position.

A sprocket 1 1 carried on a shaft 15 is connected with the sprocket 5 bya suitable flexible connection and transmits motion to a miter gear 16mounted on shaft 15 supported in bearings 18 and 19. This gear transmitspower through a pinion 20 mounted on a shaft 21 passing laterally acrossthe frame 11 and is supported in bearings 22.

A disk 24 mounted on the shaft 21 has pivotal connection with a collar25 which fits around and is set screwed to a handle 26 attached to a hoe27. The upper end of the handle 26 is fixed to slide in a sleeve 28which has pivotal connection with a support 29 mounted on the frame 11.

WVhen the disk 24 is made to revolve by the ground wheels 2 and theupper end of the handle is properly adjusted on the support 29, the hoewill be given an oscillating stroke which will thin the cotton as themachine is drawn across the field.

For adjusting the height of the frame 11 independently of the groundwheels 12, a bell crank lever 30 is pivotally mounted on a segment 31carried on the arch 9 and has connection with the bearing 18 and 19 bymeans of a chain 32. This lever is arranged to be operated from a seat33 mounted on a support 34,

An extra support 35 for shaft 15 has pivotal connection with the axle 1so that it will not interfere with the raising and low-. ering of theframe 11.

\Vhat I claim, is:

1. In a cotton chopping device, the combination of a main frame providedwith depending arch portions, wheels carrying said frame, anindependently vertically movable secondary frame slidably connected tosaid arch portions, the entire support for said secondary frame beingapproximately in a plane with said depending arch portions, a choppingdevice carried by said secondary frame, and driving connections for saidchopping device operated from said wheels the slidable connectionbetween said secondary frame and depending arch portions comprisingoppositely disposed series or rollers on the secondary frame bearingupon said depending arch portions.

2. In a cotton chopping device, the combination with a main frameprovided with depending arch portions, wheels carrying said main frame,an independently vertically movable secondary frame slidably connectedto said extensions, the entire support for said secondary frame beingapproximately in a plane with said depending arch portions, a choppingdevice carried by said secondary frame, and driving connections for saidchopping device operated from said wheels in combination with a pair ofground rollers connected to the secondary frame whereby the latter willbe automatically raised and lowered.

3. In a cotton chopping device, the combination of a main frame providedwith tion rollers mounted on said secondary frame and adapted to engagethe opposite sides of said depending arch portions, the entire supportfor said secondary frame being approximately in a plane with saiddepending portions, a chopping device carried by said secondary frame,driving. connec tions for said chopping device operated from said wheelsand means positioned approximately above said slidable connections forraising and lowering said secondary frame.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN M. MARTIN.
